PUMP-OPERATING mums.

Application filed October 11, 1923. Serial No. 687,808.

To all whom it may concern.-

Be it known that we, LINN K. PARK and Manors MANNING, citizens of the United States, residing at Houston, Texas, have mvented-a certain new and-useful Improyement in Pump-Operating Means, of which the following is a specification,

Our invention relates to hoistlng apparatus particularly adapted for use on 011 pumping installations for handling the tubing and rods when they are withdrawn from the well in the recess of cleaning or renewing the pumping apparatus. o

In the usual standard pumping rig, a band wheel isoperated from an engine to actuate the walking beam and from the band wheel a bull wheel on the opposite side of the derrick platform is rotated by means of a bull rope or hell connection with the band wheel. This bull wheel installation is heavy and expensive. It occupies valuable space onthe derrick platform. It is slow in operation and occupies a dangerous position for the operator.

It is the object of our invention to provide a small and compact hoisting apparatus, which is light, easily portable, and which may be installed adjacent the band wheel or other source of power, thereby using little space on the platform. It w1ll be safe to operate and will handle the pulling quickly and expeditiously.

Another object is to provide a ho1st1ng apparatus which may be easily reversed without strain or jar upon the operating mechanism, thereby avoiding danger of breakage when the tubing, rods or bailer catches in the well.

These and other objects and advantages will be set forth with greater particularity I in the specification which follows:

and 2 connected with the derrick and a.

Referring to the drawing herewith, wherein like numerals of reference designatelike parts in all the views: Fig. 1 is a Y front elevation of an installation embodying the invention, certain parts being broken away for greater clearness; Fig. 2 is an end elevation thereof; and Fig. 3 is an elevation viewed from the opposite end.

In the drawings, the device is shown as supported by two upright end members 1 base formed by the derrick floor 3. The cable drum 4 is mounted rotatably upon a shaft 5 supported at its ends in bearings 6, secured rigidly upon the supports 1 and 2.

The supports beinfg inclined somewhat, the bearings consist o a triangular base block 7, having a forward bearing recess 8 therein. A removable upper bearing plate 9 is clamped upon said base plate 7 by bolts or s irews 10 thus securing the shaft firmly in p ace.

The drum 4 is materially shorter than said shaft and is mounted midway thereof so that its ends are spaced from the sup ports 1 and 2. Said drum comprises a spool shaped reel having bearings 11 at each end. On the outer faces of both of the radial end flanges 12 are formed the brake drums 13 of ordinary construction adapted to receive the brake bands 14' operated by the brake rod 15 having a hand lever 16 thereon.

Immediately adjacent the outer end of each bearing hub 11 are sleeves 17, 17, having bearings 18 on the shaft 5. Fixed nonrotatably on the inner end of sleeve 17 is a collar 19 having thereon a spider 20 the outer periphery 21 of which forms a stop member for discs 22 of a friction clutch.

Slidable on said sleeve 17 is a clutch actuating collar 23 havin a toggle connection 24 with the friction disc engaging band 25. The collar 23 is slidable on said sleeve 17 by means of a lever 26 pivoted at its upper end at 27 to a cross piece 28 connected with a supporting frame. This lever is connected in the usual manner to the sliding clutch collar and at its lowerend adjacent the platform 15, it has a pivotal connection with a rod 28. 7

As will be noted from Fig. 1, the 'rod 28 is adapted to operate the clutch levers at both ends of the reel. The rod is actuated by means of a lever 29 connected at 30 to the rod 28 and at its lower end beneath the derrick platform it is connected to a rod 31, connecting the lever 29 with a lever 32 projecting downwardly from the pedal 33. This pedal is fixed to a pin 34 having a bearing upon the platform of the derrick. Said pedal is adapted to be operated in either direction, so as to connect one friction clutch with the reel at the same time the clutch at the opposite end of the reel is disconnected. When the said edal is in neutral position, as shown in Flg. 1, both clutches are released from engagement with the reel.

The sleeves 17 are operated by means of sprocket wheels 35, 36, at the outer ends of Said sleeves. Said sprocket wheels are keyed 35,- at one end of shaft 5, is connected with to the sleeves and the sprocket wheel 35 is o ratively connected with a s rocket wheel 3 mounted upon a countersha 38 by means of-a sprocket chain 39. I

The countershaft 38-is mounted upon the upright supports 1 and 2 by means of bearings 40 similar in construction to the bearings 7 for the shaft 5. The sprocket wheel the sprocket wheel 37 as previously noted,

and the sprocket wheel 36 at the opposite end is adapted to be operated by means of a chain. 43 connected with some source of The advanta es of this type of construction will be obv1ous to one skilled in the art. The device is simple and compact and occupies little space upon the derrick It may be rotated in either direction without reversing the direction of rotation of the engine and the reel may be operated by the clutch mechanism without any jerk or jar upon the operating parts by the gradual connection of the clutch to the reel. This reel may be gradually engaged while the engine is running at hlgh speed and may be likewise disengaged without any effect upon power, such as a sprocket wheel upon the the source of power. This is particularly and wheel shaft or directly with some engine or motor. The chain 43 is, as shown in Fig. 3, adapted to run the sprocket wheel 36 and also engage the sprocket wheel 4:2 so as to operate t opposite to the direction of rotation of the sprocket wheel 36. It will be noted that the operation of a chain 43 will cause the contmuous rotation both of the sprocket wheel 36 and the countershaft 38 to which the sprocket wheel 42 is connected. The connection between the sprocket wheel 37 and the sprocket wheel 35 will cause the continuous rotation of these two members, but in a direction opposite to the rotation of the sprocket wheel 36. It will then only be necessary to connect one or the other of the sleeves17 to the reel 4 by means of a friction clutch already described.

In the operation of our improved device,

" the rotation of the sprocket wheels will be accom lished in the manner described, and when it is desired to reel up the cable upon thedrum in hoisting operatlons, the friction clutch connecting the sprocket wheel 36 and the sleeve upon which it is mounted to the reel will be put in engagement, thus serving to drive the reeling mechanism in the same direction in which the engine is rotating. If it is desired to stop the reeling mechanism, the pedal 33 is employed to throw the friction clutch into neutral position and the brake is then employed to bring the reel to a stop. If it is then desired to lower the rods or tubing into the well, the weight of theparts to be lowered will be suflicient to unreel the cable from the reel 4 if the brake band is loosened through the operation of the lever 16. llf, however, it is necessary to use the motive wer to turn the reel in the lowering direction, the throwing of the friction clutch into reversing position will conmeet the countershaft 38 with the srocket wheel 35, and the friction clutch at it at end may be engaged with the reel so as to positively rotate it in the unreeling direction.

e shaft 38- in a direction will be placed in neutral position and the speed of the reel will be limited by the operation of the brake bands upon the brake drums. A. hoisting mechanism of thiskind is not only light and compact, but cheap in construction and may be operated at a much cheaper cost than the type of mechanism now ordinarily employed. It is also safer to operate and may be easily housed at the latform. v

side of the derrick. Its further objects and advantages will be obvious to those skilled in the art.

What we claim as new tect by Letters Patent is:

A hoisting apparatus for well pumping equipment, comprising upright supports, a shaft, a cable reel rotatably mounted thereon, a brake drum onQeach end of said reel, brake bands on said drums, and means to operate said reel on said shaft comprising, a sleeve on said shalt at each end thereof, a s rocket'wheel fixed on each sleeve, a friction clutch between said sleeves and said reel, a counter shaft on said supports, sprocket wheels at each end thereof, a sprocket chain connecting the .sprocket wheels on said shafts at one end thereof and desire to proand a drive chain from a source of power- Y MARGlA MANNING.
